Lucy followed up her snap with a scene of her sporting the triangle-shaped halterneck bikini as she relaxed in the hotel's infinity pool.

The reality TV babe looked super chilled as she soaked up the sun, with her hair scraped back and her arms on the water's edge.

Behind her the Indonesian island's lush landscape of huge trees and beaches made for the perfect shot.

She also uploaded a video showing her and James sharing a snog in their idyllic surroundings.

Also posted on Instagram, it showed her diving into the pool and swimming towards the bottom, before paddling up to meet her hunky boyfriend.

His gym-honed physique was on full-show as he opted for a pair of pale blue shorts.

The cute couple then enjoyed a smooch in the sunshine.

Lucy, 25, has been holidaying with her new man in the swanky Four Seasons Hotel at Jimbaran Bay.

Since touching down she has left her social media followers somewhat green with envy, posting images of the resort's picture-perfect grounds.

She uploaded a signature shot of her legs as she lay on a lounger alongside a private pool at her lush villa.

Her saucy shot may way have caught the eye of her ex Made in Chelsea co-star Millie Mackintosh.

The blonde heiress has been dubbed a "bikini queen" by her legions of Instagram fans and has been cramming her account with bikini selfies since splitting from ex husband Professor Green earlier this year.

Since calling time on their three-year marriage, the gym bunny has jetted off to a Juice Detox in Portugal as well as soaking up the sun in Ibiza and the swanky Coachella music festival.

All the while, she wasn't shy in sharing shots of her pert derriere adorned in a sexy strappy neon bikini knickers or flashing her super-toned abs in a trendy two-piece.
